Satellite archaeology researcher Angela Micol of Maiden, N.C said that the complexes were located about 90 miles apart, and contained unusual grouping of mounds with intriguing features and orientations.

One site located in Upper Egypt, just 12 miles from the city of Abu Sidhum along the Nile, features four mounds each with a larger, triangular-shaped plateau.

The two larger mounds at this site are approximately 250 feet in width, with two smaller mounds about 100 feet in width.

The site complex is arranged in a very clear formation with the large mound extending a width of approximately 620 feet -- almost three times the size of the Great Pyramid.

“Upon closer examination of the formation, this mound appears to have a very flat top and a curiously symmetrical triangular shape that has been heavily eroded with time,” the Discovery News quoted Micol wrote in her website Google Earth Anomalies.

Mysteriously, when zooming in on the top of the triangular formation, two circular, 20-foot-wide features appear almost in the very center of the triangle.

Some 90 miles north near the Fayoum oasis, the second possible pyramid complex contains a four-sided, truncated mound, which is approximately 150 feet wide.

“It has a distinct square center which is very unusual for a mound of this size and it almost seems pyramidal when seen from above,” Micol wrote.
